BRASILIA/SAO PAULO Dec 10 (Reuters) - A "truth commission" investigating abuses during Brazil's 1964-85 dictatorship called for the prosecution of former military officers and some private companies for their role in human rights atrocities, in a long-awaited report on Wednesday.

The probe's leaders presented their 2,000-page report to an emotional President Dilma Rousseff, herself a former Marxist militant who was jailed and tortured by the regime in the 1970s.
